Countershaft Assembly Disassembly and
Reassembly
S7RS0B5206020
Disassembly
1) Drive out left bearing cone (2) with 4th gear (3) from countershaft (1) using bearing puller (4) and
hydraulic press.
CAUTION!
• Use bearing puller and hydraulic press that will bear at least 5 ton (11,000 lb) safely.
• To avoid tooth damage, support 4th gear at flat side of bearing puller.
2) Apply bearing puller (5) to 2nd gear (4) and drive out 3rd & 4th gear spacer (2) and 3rd gear (3) together
with 2nd gear from countershaft (1) using hydraulic
press. Take out needle bearing from countershaft.
CAUTION!
• If compression exceeds 5 ton (11,000 lb), release compression once, reset bearing
puller support and then continue press
work again.
• To avoid gear tooth from being damaged, support it at flat side of bearing puller.
3) Take out 2nd gear synchronizer outer ring, center cone and inner ring.
4) Using snap ring pliers (2), remove circlip (1).

support it at flat side of bearing puller.
6) Disassemble low speed synchronizer sleeve & hub assembly.
7) Take out 1st gear needle bearing from shaft.
8) Remove right bearing cone (2) using bearing puller (3), metal stick (1) and hydraulic press.
Reassembly 1) Clean all components thor oughly, inspect them for
any abnormality and replace with new ones as
necessary.
2) To ensure lubrication of countershaft (1), air blow oil holes (2) and make sure that they are free from any
obstruction. 3) Fit low speed synchronizer sleeve (4) to hub (3),
insert 3 keys (2) in it and then set springs (1) as
shown in figure.
NOTE
• No specific direction is assigned to each key but it is assigned as sleeve & hub
assembly.
• Size of low speed synchronizer keys and springs are the largest compared with
those of high speed and 5th speed ones.

Synchronizer Parts InspectionS7RS0B5206021
Check clearance “a” between synchronizer ring (2) and
gear (1), each chamfered tooth of gear, synchronizer
ring and sleeve, then determine parts replacement.
Clearance “a” between synchronizer ring and gear
Standard: 1.0 – 1.3 mm (0.039 – 0.051 in.)
Service limit: 0.5 mm (0.019 in.)Put the 2nd gear synchronizer outer ring (1), inner ring
(3) and the cone (2) together and then measure the step
difference between the outer ring and the inner ring. And
also check each chamfered tooth of gear and
synchronizer ring and replace with new one, if
necessary. Also, check gear tooth.
Difference “b” between synchronizer outer ring and
inner ring
Standard: 1.0 – 1.3 mm (0.039 – 0.051 in.)
Service limit: 0.5 mm (0.019 in.)
